IMPROVEMENT IN COOKlNG-STOVE$.-

The Schedule referred to in these Letters Patent and making part of the lame.

tion of heat beneath the six boiler holes maybe at-.

tained than in ordinary cook-stoves.

Description of the Accompanying Drawing.

Figures 1 and 2 are verticalsections of our improved stove; and

Figure 3, a plan view of the same, with the top removed.

\ General Description.

Oniimprovement in cooking-stoves par-takes of the characteristics of the range for which Letters Patent were granted to uson the 25th day of October, A. D.

1870, as regards the directing of the products of cornbnstion in an undivided volume, first beneath the four boiler holes nearest the fire-place, and then around the oven and beneath the rear boiler-holes to the exitopening. A cooking-stove, however, differs so much in shape and disposal of parts from a range that, in applying our invention to a stove, a reorganization, which forms the subject of this application, and which we will now proceed to describe, was adopted.

In the drawing A is thebot-tom plate of thestove;

B, the top plate, with its six openings, at a, a a, and aid", and its exit-opening I);

l) is the ash-pit;

E, the grate, of the form usually adopted in cookingstoves; K

G, the oven; and

H, the rear plate.

At the rear of the fire-place is a plate, I, partly inclined andpartly horizontal, as shown in figs. 1 and 2, the horizontal portion terminating at the line at, fig. 3, which, it will be observed, coincides, or nearly coincides, with the centers of the two middle boiler- -holes a a, shown'l'ri dotted lines.

A shelf or deflector, J, situated between the top of the oven and top plate of the stove, projects from the rear plate II toward the middle of the rear boilerholcs.

Between the top of theoven and top plate of the stove is a valve or damper, K, which, when depressed as shown in fig. 2, permits the products of combustion to pass directly from the fire-place and beneath the six boiler-holes to the exit-opening b.

\Vhen the damper is raised, however, as shown in fig. 1, the products of combustion will turndownward beneath the middle boiler-holes, pass through the flue in front of the oven beneath the same, and upward through thc rcar vertical flue H, and on arriving at the shelf J will he directed forward by the latter and be turned beneath the rear boiler-holes before passing through the exit-opening b to the chimney.

It will be'scen, without further description, that the object arrived at, namely, a. uniform distribution of heat beneath the whole of the six boiler-holes, is

fully attained in a stove of very simple construction.

Claim. .The within-described arrangement of the oven G, fire-place F, the shelf J,- dam'per K, plate I, andflue M, for the purpose specified.

In testimony whereof we have signed our names to
